What is the primary use of the hose carried on the shoulder during deployment?

The primary use of the hose carried on the shoulder during deployment is for interior firefighting. This method of carrying the hose allows firefighters to maneuver more effectively through buildings while maintaining a ready supply of water to combat fires directly inside structures. The shoulder carry technique enables firefighters to advance quickly into a fire scene, ensuring that they can address the flames as soon as possible and effectively protect lives and property.

Carrying the hose this way also provides flexibility in navigating tight spaces and obstacles commonly found in interior environments, such as furniture and structural elements, allowing teams to efficiently reach the source of the fire. Interior firefighting often requires quick access to water, and carrying the hose on the shoulder facilitates that immediate response needed in high-combustion situations.
